Adrian Lahdo broke through at Hammarby last year. Now it is clear the 18-year-old has been lost to the Allsvenskan club.
Going forward, he will play for Serie A side Como.
At the Italian club, he gets former Spanish great Cesc Fabregas as coach and becomes a teammate of Mjällby's former goalkeeper Noel Törnqvist.
"He is a complete midfielder and extremely talented, so he will complement us. He plays box-to-box, which suits Fabregas' style of play. It will take time for him to adapt, but our environment allows it," sporting director Carlalberto Ludi told Sky Sports Italy.
According to several media reports, the deal is worth 130–140 million SEK.
